To all whom it may conoe'n:

Be it known that I, JAooB DEMAREST, of

The nature of my invention relates to the construction of a handle for knives used in Cutting leather and other such articles, and consists in a divided clamp, having a tapering thread, through which the knife-blade passes, and which can be made to hold the blade in any desired position.

In the accompanyin g drawin g, my invention is shown in section.

a represents a hollo-w wooden handle, to which the threaded ferrule b is attached. Screwin g into this ferrule is the divided clamp c, made in two equal parts, threaded, and slightly tapering upon their periphery, so thatwhen screwed up into the ferrule they will be brought closely and tightly together. Passing between these two parts up into the handle is the knife-blade e, which, by slightly loosening the clamp, can be drawn out or in, and secured in any desired position. The front ends of the clamp are formed so that it can be readclamp c, constructed and Operating as de-`` scribed, so that the blade e can be adjusted back and forth. i

In testimony that I claim the foregoing as my invention I hereunto affix my signature this 6th day of February, 1873.
